<pre>
    @page "/ShowFile/{Id:guid}"
    
    //// What to put here to let the browser render the byte array stored on this.Model
    //// Also how to specify the content type of the response?
    
    @code
    {
        [Parameter]
        public Guid Id { get; set; }
    
        private byte[] Model { get; set; }
    
        protected override async Task OnInitializedAsync()
        {
            await base.OnInitializedAsync();
            //// Gets the byte array of a file based on its identifier.
            this.Model = await this.GetFile(this.Id).ConfigureAwait(false); 
        }
    }
</pre>

如何避免foreach语句中的条件,但同时省略了可能的null元素的处理？

public class MyObject
{
    public int Value = 0;

    public MyObject(int value) : base()
    {
        Value = value;
    }
}

class Program
{
    static void Main(string[] args)
    {
        var list = new List<MyObject>()
        {
            new MyObject(1),
            new MyObject(2),
            null,
            new MyObject(4),
            new MyObject(5)
        };

        foreach (MyObject obj in list)
        {
            if (obj != null)
            {
                Console.WriteLine(obj.Value);
            }
        }

        list.ForEach(obj =>
        {
            if (obj != null)
            {
                Console.WriteLine(obj.Value);
            }
        });
    }
}
